在 Xpages 中。如何将值从 serviceBean（由 extlib REST 服务调用）传递回注释文档

Question

在 Xpages (9.0.1FP9) 中。我正在使用 extlib 从支付网关 (Braintree) 接收一个 webhook。 REST 服务/serviceBean。我从 webhook 获取包，我可以解析信息。但是我无法在 JAVA 中获取 Domino 会话的句柄，因此我可以创建或更新 Notes 文档。
我的 JAVA 技能有限，所以我被困住了。任何帮助将不胜感激。

Xpage
{
    <xe:restService id="JSONSearch" pathInfo="test1" state="false">
        <xe:this.service>
            <xe:customRestService contentType="application/json"
                serviceBean="com.mydomain.bt_Webhook1">
            </xe:customRestService>
        </xe:this.service>
    </xe:restService>
}

您可以通过从 XPages 运行时解析 session 对象来获取它，例如Session s = (Session) ExtLibUtil.resolveVariable("session");

这是 Eric McCormick 在其博客 post https://edm00se.io/xpages-servlets/servlets-handling-data-round-house-kick/ 中的代码的扩展。 ExtLibUtil 给出了他使用 FacesContext 的快捷方式。
